<br />~ . , ... <br /> <br />- , - <br /> <br />Mr. Lohlllan discussed the possibil:l.ty of drainage by P1llllping tor reuse on <br />project lands in which case the question of beneficiaries tor repayment would <br />be simplified. The ettect of drainage on present irrigation wells in the area <br />was also discussed. Mr. Lohman commented that mest of the present irrigation <br />wells were on bench lands and should not be seriously affected, although some <br />lower wells might be. It was suggested that water table data be cheoked and <br />included in the report to cover this condition. ' <br /> <br />Mr. Dorroh explained the drain yield data supplied by the Soil Conser- <br />vation Service. It was generally agreed that the drain yield would inolude <br />some water which would nonnally return to the river as irrigation return flow <br />as well as water salvage by reducing non-benet1cial consumptive use from <br />seeped areas. The drain yield data were obtained from Holly Drain records. <br />Mr. Burgess pointed out that Holly Drain records include some irrigation oanal <br />wastes and at times most of the flow of Wild Horse Creek. <br /> <br />Chairman Gildersleeve commented that approximately half of the acreage <br />to be drained would be improved only one class, and expressed doubt that the <br />benefits would justify the cost or the maintenance charges. Mr. Redmond com- <br />mented that future studies oould evaluate this question. <br /> <br />General Kr8lller asked if the quality of salvage water and suitability fcr <br />irrigation use had been considered. Mr. Ireland mentioned that several ditohes <br />below L8lllar were now diverting their supply almost entirely from return flows <br />of similar quality. <br /> <br />The subcommittee agreed that additional hydrologio studies were needed <br />to firm up the estimate by the Soil Conservation Service of the quant:l.ty of <br />water which could be salvaged by drainage. <br /> <br />The next meeting of the subcommittee will be called as additional ageMY <br />project or progr8llls data becomes available for review. <br /> <br />- c - <br />
